Paludamentum

In Republican and Imperial Rome, the paludamentum was a cloak or cape fastened at one shoulder, worn by military commanders (e.g. the legionary Legatus) and rather less often by their troops. As supreme commander of the whole Roman army, Roman emperors were often portrayed wearing it in their statues (e.g. the Prima Porta Augustus) and on their coinage. After the reign of Augustus, the paludamentum was restricted to the Emperor. Children would also wear it sometimes, when there was bad weather and they needed protection.
